To dit ficha-mei may comme.'

Be it .known that Qt'. VViLLLiar S, JoHNS, a citizen ot the UnitedStates', residing in Norwood, in the county oit Hamilton and State ofhio, have invented certain new and ut-.etui improvements in Computingines, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming part oat thisspecification.

The object ot my invention is to frnish a machine for the computation ofWages, in-l terest Land the like, and themachine is more especiailydesigned vtor determining at a he amount of Wages due for any v"'-rt otan hour, day or Week, at iate of Wages, the machine he ing designed forindicating the amount at any desired rate for fractional periods ottimecovering each tive minutes of a twelve honr day.

in order to economize space, thevarious computations are mounted oncards, or piates made oi" any suitable material, each card containing onfront and back, or on two cards or plates secured hack to back.computations irrr di'tlerent rates of Wages for each tive minute periodup to twelve hours, and for each. lioiir thereafterhup to sixty honra.

Mechanism is provided torlpresenting the proper card for the selectedrate of wages at a sight opening, 'and provision is' made 'torpri-senting .either the front or reverse laide of the card depending onwhether the -fxoniputations for the selected rate are found on the frontor back of any card. l

In connection with the card containing the computations, a fixed scaleis provided in rating each five minute period, and a sliding pointer isarranged to. be employed in connection with the proper card to indicatethe exact sum due for any period ot' time et the given rate for whichcomputation is to he made.

Pro ision is also made for deducting fromv A. to he cmputed theliinchhour, and prot on is also made for indicating the proper computationwhen the wage earner does not. commence his Work at the usual` time. f

My improvements consist of that certain novei construction andarrangementof partsl to accomplish the above results in the manner to behereinafter particularly pointed out and claimed.

In the drawings Figure 1 is a'plan View of my improved machine. Fig. 2is a side `elevation of same. 'l1`ig. 3 isa plan ieiv at one side of oneof thelcai'ds containing the exact coihputation. Fig. It is a centralvertical cross section of the machine. F ig. is a detailed crosssectional view illustrating the method of selecting and presenting thedesired card at the sight opening.'

l2 is a cross section on the lines ficy of 1l. Fig. 13 is a perspectiveview` of the pointer construction for automatically deducting the lapsedtime. FigLl-jl is a. plan view of saine.

The operating parts are inclosed in an L-shaped box consisting ot a hase1, bac-lr Wall 2, and top plate 3, for the vertical extension of thecase, top plate -t the Mr'ont of the case including a lglass plate :3,through which the cards are exhibited, and Afront Walls 6 and 7 andanintermediate partition 8, for the casing.

VMounted horizontally in the vertical portion of the case in the sidewalls, is a shaft 9, which is rotated by finger buttons 10, l0 fromeither side of the oase. This shtift carries at each end disks 11, 11secured thereoii, and these disks are provided `with a series of radialslots. each designed to hold a card 13 upon which the computations aremade. These cards are preferably each provided with a binding frame '14,and the frames areprovided with trunnions 15, l5 Ato rest in the slotsl2, l2. In order to prevent the frames and cards'from falling out of theslotted holder, as the holder is ro-, tated, a sheet metal shield orguard plate Y the low half of the holder. Each of these mwah-'Sideflanges 1S provided to incase cards fgi' the particular' purpose .torwhich -Ihzi-vede'signed my machine, contains four horlzontal rows ofAcomputations as illus- 4 trated in Fig. v3. Thetwo lower ro'ws containthe computations for the amount of wages at any 'selected rate or eachtive minutes of time up `to twelue hours. The

uppermost row indicates each hour from` 13 to 60, and the figures in theow'next the top contain the-computations for\the indicated hours at theselected rate. Each card is provided with these' computations "on thelIn order to select the proper. card con-4 taining the computations forthe desired wage rate, I provide as followszl? is acylinder mountedhorizontally in the casing and provided lwith a series of'radiallyextending and spirally arranged lugs 18,' two` vfor each of the thirtydifferentcards, and this cylinder is p geared to the idler gear 19 by agear 20, and .thefidler is gearedwith the gear 21 on the shaft 9 asshown in Fig. 8. The' lugs 18 on the cylinder 17 are so arranged'withreference to theslots 12, in the cylindrical card holder, that whe'nanyparticular lug reaches .-a certaln jposition, the

proper card for that lugfwill restits trun-v nion head 22 in the slottedholder 23, which lis mountedon the 'end of a lever arm 24 pivoted in abracket 25 on the partition wall 8 near the bottom of the case:

'-Inorder to stop the cylinder 17 at the proper point, and thus throughthe train of gearing 19, 20 and 21 to stop the cylinder holder at theproper point, I provide as follows Projecting through the front w-all 74of` the case are two series of horizontallyarranged -push pins 26 and27, provided with heads 28, 29 upon which heads are 1n-v dicated the'various rates of wages, there being sixty'of these pushbuttons inthe'two series, the upper series having relation wlth the front 'facesof. the computation cards,'

and the lower series having lrelation to the reverse side of thesecards.

The operator. pushes .1n the proper push i button for the rated'esred,and that project-stheinner end of the pin 27 in the path-V way of theproper lu 18, .oror-the push pins 26, projects the v epending arm 30 inthe pathwayof the proper lug 18. In this way the card holderlwill -bestopped at the y proper point with the endsof the` trunnions of thecards resting in the slotted holders 23, ,carried by the arms 24,mounted on the rock shaft 31 Aat'thc bottom of the case. This rock shaft31 is actuatedby the hand crank 32 outsidethe case, and carries 'theselected, card with the swing of the lever 24 forward toward the frontof the case;

As the computation cards carry thev computations on both sides, it willbe necessary to reverse the card whenever the `wage rate .selectedappears on the reverse side of the card, in order to display the properset.

' computations through the glass window 5.

Each pin 26 carries a stud 33 which rides.

in the pathway ofthe lever;34, mounted on a -rock shaft- 35, which shaftis connected at either end,with toggle levers 36, 37, the toggle leversin turn 'carrying the depend ing racks 38, at either end and arrangedy'to slidevertically in suitable guide blocks '39.' As the push pin 26is pushed in, the toggle levers-will be straightened out and depress theracks 38,`so that they` will be engaged by the gears 40 mounted on and a,part of the holders23, pivotally mounted on theendsf the rock levers24. As the hand crank 32 is turned, therefore, this c nlgagement f thepihilbns 4() with the racks 38, will-rotate', the slotted holders 23 ahalt turn -and'vrevelieA the card. To prevent the holders ffromfhecoming disconnected from thel cards during' this'rotzition, I provideside arms 90, 90,:/w'hich extend around the holder 23 and .pinionf40 sothat as the' holder rotates it cannot move away from the' card.

In order to return the push pins 26 and 27 .to normal position, I.provide the lever arm 41 mounted on' `.the pin 42,'. and thf' upper end-of `this llever V41 isv'engaged bythekle-A pending'arms 43 on the shaft44. This shaft 444 carries a separate arm 46 for each'push pin 27, whichlies in engagement with the stud 45 on each of these pushpins) Thepushing in of the pins 27 carries theflever arms 41 in the pathway ofthe arm24 'which carries the slotted holders 23, and fas the Vslottedholders 23 and the arm 24l are returned to normal by turning back thehand crank 32, the levers 41"rock the shaft' 44 which, in turn,carries-'back the push pin 27 to itsiiormal position. Each ofthel arms46 is'also coupled by links 47 to the depend ing portion 30'of the pushpins'26, so that if an upper push `pin basl-'been lactuated the Vreturnof the card 'carrier will in the same way return to normal position,.thepush pins 26. The return ofthe' push pins 26 to their normal'p0siton,does notv return the rack Vbar 38 as the studs4 33 only contacton one. ,side with the arms 34, and so long as 'the upper rowof'pushpinsis used, the rack req mains depressed so as tolie `engaged by'the pinion 40,...

The arms 34 are extended downward from the rock shaft' 35, as indicatedlby dotted lines in Fig. 5, so as to be in the pathway of the studs onthe pins 27, and when any push pin of the lower row is operated, thecontact of the stud 45 thereon with the depending portion of the arm 34will rock the shaft 85,' and raise up the rack bar 38 so that the pinion40v will not beengaged thereby, and the selected card will. .not be reversed. v

Having thus selected and presented at the sight opening 5, the propercard containing the computations, it will next be necessary to ascertainthe amount of wages for the particular time selected. The mechanism forselecting the time is mounted in the upper portion of the front half ofthe cas ing.

is a fixed scale secured along the edge of the sight opening 51 underthe protecting glass 5. This scale is graduated for a period of twelvehours and into tive minute spaces for each hour. The hours are marked onthe scale to indicate the hours of the day from 6:00 or 7:00 a. m., to6:00 or 7:00., p. m., or otherwise as the case may be, and

. the hours are also marked from` one to twelve.

is a pointer slidable along this scale, the pointer and its slidingattachments being best illustrated in Figs. l0, ll and 12. The pointeris secured to a block 53 which extends across the top plate 4 of thefront portion of the machine, and the block carries the guide portion 54which is inserted in and rides back and forth in the slot 55 in the topplate 4. The transverse block 53 is divided into an upper and lowersection 56, 57, and the two sections slide on the top plate 4, the oneabove and the other underneath the plate. The two sectionsl 56 and 57are provided with horizontal slots 59, 60 and the upperportion is alsoprovided with the segmental slot 61, through its top plate and the lowersection 57 is provided with a dortailed groove 62 running lengthwise ofthe section.

63 is a lever pivoted on the pin 64 at the outer end of the guideportion 54, and this lever is rocked by the handle 65 secured on theinner end thereof, which passes up through the slot`61. At its lower endthe pin y64 carries another lever 66 which enters the slot 60, and has aslotted connection with the block 67, mounted in the groove'62 to slidetransversely. and the lower end of this block 67 has projecting anL-shaped stud 68. It will be evident from this` construction that as thehandle 65 is moved back and forth, that the L-shaped block 68 will bemoved transversely along the lower face of the slide construction.

Atlixed to the pointer 52 isla; bar 69,

which carries a second pointer 70 adjust able thereon by the lhandle71'. This/,barffs mally the pointer 70 is pushed upto register with thepointer 52, and if in making use of the machine the number of hours andminutes are to be calculated from` the first` hour time, say elevenoclock, the y merely moved to-the desired ,houcax'id' ,the

ive minute period indicated 0n theiiixd Y scale 50, and the pointerwillfthenfbe .dni-` 65;A graduated into ve minute periods.y Norf 1 Y70shown on the fixed scale 50, until some, later Y inter is rectly overthe amount indicated oiithe proper rate of wages cardf forathatparticu-l lar period of time. If thetime to be Vcalculated must omitsome recess period such as thirty minutes for lunch, the pointer 70`ismark, and the party making the calculation proceeds as before, butintsead of reading from the pointer 52 on the card `he reads from thepointer 70. Now if ithappens, however, that the time is not to becalculated from the first hour shown on the fixed scale 50, but say fromnine oclock until 2:30 the operator slides the pointers 52 and 7 0 whichare normally together, back to the nine oclock hour, and then he movesover the handle 65 toward the front of the machine n 74, 74, one rackfor each groove 'and each` rack 74 provided with twelve slots 75, one

72 secured' between each tooth and corresponding to f the tive minuteperiods of the scale 50. Each of these racks 74 has a transverse lugl76at each end, and extending in oppositeidirections so that as the racksare pulled out theyv will become coupled to each other, and theinner-most rack has secured to it a. pointer 77, like the pointer 52,'and this pointer 77 is also provided with a sliding bar 78, carryinganother pointer 79 with the scale of five minute periods graduated onthebar 7 8, and the bar 78 normally carried with the handle so that thetwo pointers 77 and 79 coincide.

Now when the wages are to be calculated from some hour later thanthecommencell nient of the scale` when the operator moves the handle 65 itwill cause the L-shaped lug Y 68 to engage in one of the slots of one ofthe 1 sliding racks' 74. and will thus couple the main slide 53 to thepointer 77. The main pointer 52 is then moved to the proper time on thefixed scale 50, but the reading is taken from the pointer 77. In thesame Way 4"for the lapsed time. in this event the pointer 79 is adjustedfor this interval and the reading taken from the pointer 79.

As soon as each computation 1S taken down from the card as indicated the80 moved on the scale 69 to the thirty minute y A pointer, the .operatormoves back the handle 65- 'to normal position and the racks beingthusreleased, those that have been moved are returned to their normal.osition by the descentof the weight 83, which is mounted on the flangedroller 8 4 riding on the inc lined track 85, the end-of the innermostrack bein secured by a cord 8l running over the ed pulley 82 to thisweight. It will, of course, be understood that a spring of any suitablekind may be substituted for the weight; The operation of my calculatorwill be vevident from the foregoing description: Let us assume that theuser desires to ascertain th'e amount duev on a. number of time cards ofworkmen at dif- 'ferent ratesof wages, and for varying periods of time.The operator first presses in the push button 28 or 29 which indicatesthe rateof wages, and then turns the knobs 10 toward him until thecylindrical holder carrying the computation cards is stopped. As abovedescribed, the holder willl stop with the properl card resting 'in theslotted holders 23. The operator then turns' the hand crank 32, whichcarries forward the proper card under the sight window 5, the "cardbeing reversed if-'any push buttons in the upper row have been actuatedand not reversed in case the selected rate of wages 'is found on thelower row of push buttons,

and such push button hasbeen actuated. As it very rael happens that thecomputation desired willyextend beyond'the twelve hour period, in orderthat only the two lower rows of computations s hall ordinarily be visi-`ble through the window 5, I provide the sliding cover 91 whichordinarily conceals the two upper rows ofv computations on the card, butwhich cover can be pushed back into the case when desired.

The operator having adjusted the pointer 70 for the amount of time .tobe taken out, 'then for all the computations which are to be figuredfrom the first hour on the fixed scale, the operator merely slides thevpointer 52 to the time indicated and takesI down the amount shown on thecomputation card yopposite either the pointers ,52' or 70 depending onwhether any time is to be omitted for the periid for which the wages areto be calcu-V late For all 'those computations to.V be made where theparty has not commenced at the 65` commencement hour of the scale`,jtlie.oper` atorzhas to actuate the handle 65 to connect vthe slide withthe racks which carry the 1pointers 77 and| 79. With each of thesecalulatious, the operator pushes back-the han- 60dle 65 as shown, afterthe roper, amount has been read from the car and; lie-then proceeds as"before in vconn ectloivltlik the next calculation. i While I haveillustrated and described my calculator connection with the calculationvof wages, 1t wlll be evident that the same v construction of theapparatus could be readily use d'for the calculation of interest bymerely substituting interest cards for vwage calculation cards, and thesubstit tion of a dltferent -scale vfrom the -one illust-rated herein.

`Har'vingthus described my invention what I claim as new and desire tosecure by Letters Patent, is;

1. In a device of the character s ecified, 'the combination with a fixedscale, o a mov-. able holder,`and a series of cards, provided withcomputations at'a predetermined rate for each card imprinted on saidcards on front and reverse side, said cards being mounted insaid holder,a series of stops one for' each card to stop the holder at the deliv`ery position for said'selected card and means for transferring theselected card with front or reverse 'side into alinenient with saidfixed scale.
